VoiceMod Mobile App not working?

So I installed the Mobile App, and it was working for all of about 5 minutes.
It changed my voice in real time through the phone, I could hear myself and everything like I wanted it to, but then for whatever reason, it stopped working entirely, and whenever I would tap a voice, it would just say in the loudest volume possible
"Change your voice in real time with VoiceMod" Every time I tapped a voice changer, and then do absolutely nothing after..
I don't know how to fix it, I've done everything from clearing the cache, to re-installing it.
Someone help please, I'm not desperate, but this is an extreme annoyance.
